Upgrading Existing Eclipse Features

Eclipse Galileo (3.5) and beyond

To upgrade installed software, do the following:

Help > Check for Updates

If updates are found, proceed through the install wizard and click Finish at the end

If you are upgrading the platform itself, when you are prompted to restart it is strongly recommended to do so. A restart may not be required when updating other features, but always select to restart if you are unsure.

Note, to upgrade from Galileo or Helios to Indigo (3.7), you first need to add the Indigo software repository as follows:

Eclipse Ganymede (3.4)

Select one or more installed items to be upgraded. If nothing is selected, it will search for updates to all installed software

Select 'Update', and proceed through the wizard if updates are found

Eclipse Europa (3.3) and below

Run the Update Manager, using

Help > Software Updates > Find and Install...
> Search for updates of the currently installed features

The Update Manager will visit the Update site(s) for all your installed features/plugins and offer updates if any exist.

However, in Eclipse 3.3 or earlier, it is NOT possible to upgrade the Eclipse platform itself, only its features. So, you could for example upgrade the CVS feature or the PDE feature from 3.2.0 to 3.2.1, but not eclipse.exe itself.

Fresh install

Occasionally you won't be able to upgrade Eclipse or certain features due to incompatible changes in the update technology. In these cases you will need to download a fresh install.
Download a new build from the Eclipse download Web site (http://www.eclipse.org/downloads) and unzip it in a new directory. We strongly recommend against unzipping over your existing Eclipse version as unexpected side effects may occur, including (but not limited to): nausea, vomitting, shortness of breath, corrupt installation.

Complete upgrade instructions are always included in the Eclipse readme_eclipse.html file included with every build in the readme directory.

Windows specifics

Upgrades may require administrator privileges to succeed and may fail with error messages claiming "Only one of the following can be installed:" otherwise. Start Eclipse with "Run as administrator...".
